@Rajahten,
i have a wiikey 1, i softmodded a long time ago also, back when using the twilight hack, and have continued to softmod a few times since then for homebrew, usb loaders etc.
Follow the guide linked above on gbatemp and you'll be up to date 4.2, and with a backed up nand, priiloader, homebrew channel in no time and it'll open up a lot more potential for your wii than just the crappy ass wiikey, and its easy to do.
You got two choices in guides imo, the above one on gbatemp, which is a point to point guide, easy to follow and you get it done in no time at all. OR, the other completesoftmod guide which is more detailed and explains what you're actually doing more, but requires more reading, although is great if you have no idea and want more idea on what it all does.
gbatemp quick and easy guide
gbatemp quick and easy guide to 4.2
complete softmod guide
more detailed softmod guide in case you want a bit more knowledge
Both will get you to 4.2 and with the required cIOS files installed on your system to play galaxy 2 no worries, as well as use Neogamma, or even usb loaders if you wanna go down that path.
